5Result: The last mutation site was due to proline 579 codon ""CCA"" (reference sequence) being replaced by leucine 579 codon ""CTA"" (
P579L) in all four patients."
Figure: (A) The align of Korean
COVID-19 and wild ype SARS-CoV2
spike gene amino acid sequence revealed three new mutations (
G504D/
V524D/
P579L) highlighted by green with red letter.
Figure: The representative chromatography of
D614G (A),
G504D (B),
V524D (C), and
P579L (D) mutation was shown from the DNA sequencing results of four Korean
COVID-19 patients.
